Abstract

Money laundering continues to pose significant challenge for banks and financial institutions in the City of London and the British Overseas and Crown Dependent Territories. In this study, the phrase “City of London” is used as a euphemism for the broader UK financial sector and economy, rather than solely referring to the geographic “Square Mile.” This approach follows common usage in financial and legal scholarship, where the term functions as shorthand for the UK’s global financial hub and its interconnected institutions. Clarifying this usage at the outset avoids ambiguity and ensures that references throughout this work are interpreted in their wider economic and regulatory context. Despite rigorous compliance efforts and the implementation of international anti-money laundering (AML) regulations, financial crimes persist, exploiting regulatory gaps, jurisdictional complexities, and variations in enforcement intensity.

These vulnerabilities are particularly acute in financial hubs and offshore centres, where the interplay between economic interests and regulatory oversight creates fertile ground for illicit financial flows. To deepen the comparative dimension of this study, I expanded my research to include the operational and regulatory approaches of AUSTRAC drawing on both secondary sources and an in-depth interview with its CEO, Brendan Thomas. This allowed for a detailed comparison between AUSTRAC’s strategies in combating money laundering and the approaches taken in the City of London and the British Overseas and Crown Dependent Territories.

The comparative analysis highlights key differences in regulatory culture, enforcement priorities, technological adoption, and the integration of intelligenceled frameworks in detecting suspicious financial activity. This expanded scope underscores that while AUSTRAC operates within a single jurisdiction and leverages strong inter-agency cooperation, the City of London and its associated jurisdictions often contend with fragmented oversight and competing policy priorities. By examining AUSTRAC’s proactive data analytics, targeted industry engagement, and capacity to impose enforceable undertakings, this study identifies potential best practices that could be adapted to the UK context. Accordingly, this research aims to analyse the underlying causes of regulatory failure in these high-risk jurisdictions and to assess potential solutions for enhancing the effectiveness of AML measures.

By focusing on the unique vulnerabilities present in the City of London, the British Overseas Territories and the Crown Dependencies—and contrasting these with AUSTRAC’s centralised and intelligence-driven model—this study provides a comprehensive evaluation of the challenges facing AML efforts. It also explores potential strategic regulatory reforms, including legislative enhancements, strengthened cross-border information sharing, and more dynamic enforcement mechanisms. Ultimately, it evaluates the role of possible legal reforms in fortifying existing AML strategies to address the persistent threat of the money laundering and related financial crimes.
